István Beregszászi

full stack software developer


I'm a professional full stack developer specializing in web application backends written in modern PHP. Being able to wear other hats, I'm happy to participate in product development, building user interfaces, technical writing, keeping in touch with customers, and more.

I take pride in practical software and thoughtful design.


Senior Software Developer
Prezly July 2021 — …

Architect, Lead Developer
Crosssec Solutions Kft. August 2016 — June 2021

Leading development and deployment of a SaaS production tracker and analytics software for manufacturing companies, my goals are:

  • balancing between feature velocity and low technical debt in long-term software projects;
  • abstracting & automating key concepts such as data access management and other error-prone development tasks;
  • guiding business requirements to maximize usefulness;
  • writing comprehensive and potentially enjoyable technical specifications;
  • increasing developer productivity via side tools and workshops.

Software Engineer
Polisys Kft. October 2013 — August 2016

After landing this job through internship, I became responsible for:

  • developing and maintaining several mid-sized e-commerce sites written primarily in Symfony and Sylius;
  • designing internal tools and customer-facing products both from a technical and visual standpoint;
  • maintaining legacy applications, integrating them in modern frameworks to constrain technical debt.

Software Developer
FaceySpacey Technologies, Inc. December 2009 — May 2011

In developing a location-based advertising platform called SnackSquare, we hit the front page of TechCrunch once. My responsibilities were:

  • architecting APIs and implementing highly interactive web interfaces using the Yii framework;
  • overseeing the work of other remote developers;
  • writing detailed documentation both technical and targeted at end users.

Tinkering at home
Non-stop since I was 12

Side-projects never stopped piling up in my archives:

  • a featureful Turing machine simulator (degree work using Elm);
  • programmed a skeleton prototype of a multiplayer top down shooter game in C++ (one with tanks, obviously);
  • using Haskell, designed and deployed statically generated product catalogs for my wife;
  • my career began by making lots of fancy looking effects with JavaScript and SVG for fun (like the background of this resumé).
